 * If your inventory stock count or cash box amount does not match

-  To fix cash amount to reality in which you counted 1234Kč, use
-
-		./brmbar-cli.py fixcash 1234
-
-  whereas to fix amount of a particular stock, use
-
-		./brmbar-cli.py inventory-interactive
-
-  then scan the item barcode and then enter the right amount.

-
-* If you want to get overview of the financial situation, run

-
-  * Cash - how much should be in the money box
-  * Overflow - how much cash is stored in overflow credit accounts (pockets of admins)
-  * Inventory - how much worth (buy price) is the current inventory stock
-
-  I.e., cash plus overflow plus inventory is how much brmbar is worth
-  and cash plus overflow is how much brmbar can spend right now.
-
-  The following items represent "virtual" accounts which determine
-  the logical composition of the assets:
-
-  * Credit - sum of all credit accounts, i.e. money stored in brmbar by its users;
-    i.e. how much of the assets is users' money
-  * Profit - accumulated profit made by brmbar on buy/sell margins (but receipts
-    and inventory deficits are subtracted); i.e. how much of the assets is brmbar's
-    own money
-  * Fixups - sum of gains and losses accrued by inventory fixups, i.e. stemming
-    from differences between accounting and reality - positive is good, negative
-    is bad; this amount is added to profit on consolidation
-
-  The total worth of the material and virtual accounts should be equal.

+In the future, brmbar-cli.py will support this, but there is no
+implementation yet; it's not entirely clear yet what is the proper

+can use SQL INSERTs to manually create a transaction with appropriate
